Boring in Different Localities in Karachi

Water is being supplied to Karachi from a considerably distant located water source through bulk conveyance system comprising of a complex network of canals, conduits, siphons, multi-stage pumping and filtration.

Karachi gets 650 MGD of water from Indus River and Hub Dam sources. While, according to Karachi Water and Sewerage Board, the city population needs minimum 1200 MGD of water, which means that Karachi gets 550 million gallons of water less than it actually needs. Moreover, the water distribution management system in Karachi also has certain inherent problems. Much water is lost because of the leakage and seepage in the dilapidated pipelines.

Under these conditions, water scarcity is a widespread phenomenon in old Karachi areas. The situation does not foresee any improvement as the gigantic K-4 Project to supply water from River Indus to Karachi is going to take many more years to complete.

Because of the flawed water distribution system of the Karachi Water and Sewerage Board (KWSB) and persistent deficiency of water in the city, the water scarcity gets more severe during summer.

To obtain potable water from underground sources, boring is carried out under Dua Foundation in the rural areas and katchi abadies in Karachi.

In most of the areas of Karachi, underground water can be reached at a depth of 100-200 feet. Much of it is not sweet and it can be used for purposes other than drinking. However, at some places water with a TDS (total dissolved solids) of less than 1000 mg/L is available and it can be used for drinking purpose.

It is common to install a hand-pump or a submersible pump after the boring so that sufficient quantity of water could be obtained without any problem.
